Struct cam_geom::PerspectiveParams

pub struct PerspectiveParams<R: RealField> {
    pub fx: R,
    pub fy: R,
    pub skew: R,
    pub cx: R,
    pub cy: R,
}

Parameters defining a pinhole perspective camera model.

These will be used to make the 3x4 intrinsic parameter matrix

[[fx, skew, cx, 0],
 [ 0,   fy, cy, 0],
 [ 0,    0,  1, 0]]

These parameters describe the intrinsic parameters, the transformation from camera coordinates to pixel coordinates, for a perspective camera model. For a full transformation from world coordinates to pixel coordinates, use a Camera, which can be constructed with these intinsic parameters and extrinsic parameters.

Read more about the pinhole perspective projection.

Can be converted into IntrinsicParametersPerspective via the .into() method like so:

use cam_geom::*;
let params = PerspectiveParams {
    fx: 100.0,
    fy: 100.0,
    skew: 0.0,
    cx: 640.0,
    cy: 480.0,
};
let intrinsics: IntrinsicParametersPerspective<_> = params.into();

Fields

fx: R

Horizontal focal length.

fy: R

Vertical focal length.

skew: R

Skew between horizontal and vertical axes.

cx: R

Horizontal component of the principal point.

cy: R

Vertical component of the principal point.

Trait Implementations

impl<R: Clone + RealField> Clone for PerspectiveParams<R>

fn clone(&self) -> PerspectiveParams<R>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<R: Debug + RealField> Debug for PerspectiveParams<R>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de, R> Deserialize<'de> for PerspectiveParams<R>

where R: Deserialize<'de> + RealField,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<R: RealField> From<PerspectiveParams<R>> for IntrinsicParametersPerspective<R>

fn from(params: PerspectiveParams<R>) -> Self

Converts to this type from the input type.

impl<R: PartialEq + RealField> PartialEq for PerspectiveParams<R>

fn eq(&self, other: &PerspectiveParams<R>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<R> Serialize for PerspectiveParams<R>

where R: Serialize + RealField,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
